Application filed February 25, 1919.

To (ZZZ whom it may concern:

Be it known that 1, JOHN A. Coornn, a citizen of the United Fstates, residing" at Callaway, in the county of Custer and State of Nebraska, have invented new and useful improvements in Stackers. of which the following is a specification.

My present invention pertains to horsepower staclrers; and it consists in the peculiar and advantageous over-shot stacker, and in certain combinations and adaptation of parts thereof as hereinafter described and definitely pointed out in my appended claims.

In the accompanying drawings, hereby made a part hereof:

Figure 1 is a side elevation of the stacker with the swinging; elevator in its uppermost position.

2 is a similar view with said elevator in its lowermost position in readiness for loading.

F 3 is a plan View with the elevator in the latter position.

Fig. 4- is a view taken at right angles to Fig. 1 and showinsr the swinging elevator in its uppermost position.

Figs. 5. 6 ans 7 are detail views hereinafter specifically referred to.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

My novel stacker comprises amonq other elements a base or ground frame 1, Fig. 6. a swinging elevator 2 for the hay or other substance to be stacked, a swinging crane 3, Fig. 5, and a buiier 4:. Fig". 7, for limiting the forward movement of the elevator and equipped to impart an initial return impu se to the elevator.

In the present and preferred embodiment of the invention the base or around frame 1 is made up of spaced side bars 5. crossed braces 6 interposed between and connected to the same. bearing blocks. 7 bolted to the said bars 5 adjacent to the ends thereof. and tubular rods 8. 8 held by the said blocks 7: the rod 8 being extended laterally bevond the side bars 5 as shown.

By reference to the drawings and particularly to Fig. 3 thereof the elevator 2 will be understood as comprising side arms 9. pivoted. to swing vertically and carried on the extended portions'of the rod 8. a set of spaced tones or teeth 10 extending in the same general direction as the arms 9, cross Specification of Letters Patent.

Fatented Feb. 8, 1921.

Serial No. 279,067.

The buffer a carried upon the transverse rod 8 is formed by two spaced uprights 16, an upper bar 17 fixed to and extending laterally outward beyond said uprights a lower cross-bar 18 also fixed to the uprights 16, and crossed braces 19 interposed between and ixed to the uprights 16. My novel buffer serves to start the elevator 2 ba kwardly subse uently to the unloading of the elevator, and it is efiicient inv action and susceptible of ready adjustment.

Connected at their lower ends to the side bars 5 of the ground frame 1 are rods 20; the said connection being effected by (lips 21 which are clamped on the said side bars 5 and are adjustable on the bars in the direction of the length thereof and adapted to be adjustably fixed thereto. Interposed between and connected to the upper ends of the rods 20 and eye bolts 22 are retractile springs 23 which are put under tension when the elevator 2 brings up against the buffer 4 and are adapted by contracting to move the buffer d backwardly to a limited extent and thereby start the empty elevator on its backwardmovement to the position in which the elevator is loaded.

The eye-bolts 22 are connected to the bar 16 The crane 3 is carried by the transverse rod 8 and is constructed as best shown in Fig. 5, 2'. 6., comprises two upwardly con verging bars 24: joined at their upper ends. and cross-bars 25. Adja "cut to its upper end the said crane is equipped with a hook 26 for the connection of pulleys. Also carried adjacent to the upper end of the crane 3 is a staple 26 between which and the side bars of the elevator 2 are interposed twelve-foot rods 27 the said rods being preferably connected with the frame side bars through the medium of eye bolts 29. as shown.

The pulleys and cables complementary to my novel stacker are relatively arranged as shown, and from this it follows that when the elevator 2 is on the ground in readiness for loading, the crane 3 will rest in a position slightly inclined from the vertical in a direction away from the butler l; also, that incidental to the upward and forward movement of the elevator, the crane 3 will swing toward the buffer l and downwardly. When the elevator 2 brings up against the butter and puts the springs 23 under tension the elevator will be discharged oi its load, whereupon the retraction of the springs will through the buffer l start the elevator 2 back toward the loading position, and during the backward movement of the elevator the crane 3 will be restored to the upstanding position slightly inclined away from the butter 4:.

I prefer as shown in Figs. 1, 2, 3, l and 5 of the drawings'to equip my novel stacker with ground wheels; the said wheels being designed to facilitate movement or" the stacker "from place to place, and being carried on the transverse rod 8 of the ground frame 1. I

I have entered into a detailed description of the construction and of the parts em braced in the present and preferred einhodiment of my lnvention in order to impart a Full, clear and exact understanding of? said embodiment. I do not desire, however, to be understood as confining inyseli to the said specific construction and relative arrangement of parts as in the future practice of my invention changes in the form and arrangement of the parts may be made within the scope of my appended claims.

Having described my invention what E claim and desire to secure by Letters Patupright swinging butler, a frame to which said buffer is pivotally connected, retractile springs, the upper ends of which are connected with the upper portion oi the butter, recs connected to the lower ends of the springs, and clips at the lower of the rods adjnstahly fixed on and movable lengthwise of the side bars of the said frame.

2.511 over-shot stacker, comprising a ground frame having side bars, braces between the same, blocks on the side bars, and transverse rods in said blocks, a vertically swinging elevator having tangs dis posed at right angles to each other and also having arms connected, to one of the transverse rods of the ground frame and also having exterior braces between the tang carrying means and the side arms and interior hraces between said means and the said arms, a butter carried by said transverse rod of the ground frame, tension means between the frame and the buffer,

and adjustable on and adjustably fixed to the side bars of the frame, a vertically swinging crane on the ground frame, rods interposed between and loosely connected with th ground frame and the elevator, and pulleys and cables relatively arranged, substantially as specified.

In testimony whereof 1 JOHN A. ()0

afi'ix my si nature 'ienn.
